## Second Brain Labs (Sbl.so)

Second Brain Labs is the company behind Sbl.so, an autonomous AI SDR platform for outbound sales. The site now lives at sbl.so, and the product has narrowed into a clear proposition: run LinkedIn and WhatsApp outreach at scale without putting your own account or your team's calendar at the mercy of manual copy-paste follow-up. The core mechanic is a fleet of dedicated, pre-warmed SDR profiles — described as carrying zero account bans across 50 million-plus messages sent — so outreach volume grows without risking the founder's or a rep's personal network.

Getting started is deliberately simple. You define your ideal customer profile in plain English or import a Sales Navigator search, and the platform builds a live lead list from buying signals such as job changes, funding announcements and competitor monitoring rather than from purchased lists. The AI then opens from your sender profiles in a conversational tone, uses voice clones and rich media where appropriate, handles replies and objections, and flags hot leads for human handoff when needed. Qualified buyers book directly into the calendar over Google Meet.

Under the hood it packages roughly 18 tools into a single subscription: lead generation, AI outreach, managed sender profiles, a unified inbox, a built-in CRM with booking, advanced analytics, multi-channel sequencing and agency-grade workspaces. The platform is marketed heavily at founders running outbound without a sales hire, sales teams wanting more meetings per rep, and agencies who need a separate, isolated workspace and sender profile per client.

**Pricing & Plans:** Free trial and paid plans. There is a 7-day free trial with no credit card required and a 90% money-back guarantee mentioned on the site, plus recurring promotions such as 20% off the first three months. Plans appear to be tiered by volume and features, so check the Sbl.so pricing page for current numbers.

- **Autonomous AI SDR profiles:** Outreach runs from dedicated, pre-warmed sender profiles that rotate automatically, so your personal LinkedIn account is never at risk.
- **Intent-based lead generation:** The platform watches LinkedIn for buying signals, including job changes, funding news and competitor engagement, and builds a live lead list that updates daily.
- **Conversational AI that books meetings:** AI opens in your voice, handles replies and objections, and books qualified buyers straight into your calendar over Google Meet.
- **Multi-channel outreach:** Reach prospects on LinkedIn, WhatsApp, email or phone, with personalization, AI voice notes and sharing of images, video and files.
- **Unified inbox and built-in CRM:** Every conversation and meeting lands in one place with two-way CRM sync, real-time analytics, mobile app and unlimited workspaces.

**Strengths:** Sends from dedicated SDR profiles rather than your personal LinkedIn account, which addresses the biggest risk in outbound automation; Lead list is built from intent signals instead of purchased lists, so reply rates are higher; Bundles lead gen, outreach, sender profiles, inbox, CRM and analytics into one subscription instead of stacking tools; Agency-ready with unlimited workspaces and a separate profile per client

**Limitations:** LinkedIn automation always carries platform-policy risk, even with the account-safety design; The full value depends on ICP definition and message quality, so setup effort is not trivial; Pricing is quote-driven, so you need to talk to sales to compare plans properly at scale

## Wingflow

Wingflow helps founders, sales teams, and agencies turn LinkedIn connections into real conversations. You import a qualified list of prospects from LinkedIn search, Sales Navigator, Recruiter, or the people who liked and commented on a post, and Wingflow fills in role, company, and location automatically. You then build a reusable sequence of actions such as visiting a profile, liking a post, commenting, sending a connection request, messaging, and tagging. Personalization tokens insert each prospect's name, company, title, and location, with fallbacks for missing details.

The platform sends the sequence from the cloud at a human pace, inside your daily limits and working hours. Follow-ups wait for a connection to be accepted rather than firing on a timer, and the sequence cancels instantly across all campaigns as soon as someone replies. Multiple LinkedIn accounts can be run from one workspace, each with its own campaigns, limits, timezone, and dedicated proxy.

Replies from every connected account land in one unified inbox with full contact history, so you can answer from the right account without switching tabs. Wingflow also includes a blocklist for companies, domains, and profiles, and refuses to enroll the same person in two campaigns. It is an independent product and is not affiliated with LinkedIn Corporation.

**Pricing & Plans:** One plan at $49 per LinkedIn account per month with every feature included. A 7-day free trial is available (card required, charged after the trial). You pay only for the accounts you connect; regular LinkedIn accounts work and Premium raises the daily invite limit.

- **Cloud-based sending:** Sequences run from the cloud with a dedicated proxy per account, so nothing depends on your browser being open.
- **Multi-step personalized sequences:** Combine visits, likes, comments, connect requests, messages, InMail, and tags with personalization tokens and fallbacks.
- **Stop-on-reply:** The moment a prospect answers, every remaining step in every campaign is cancelled automatically.
- **Unified inbox:** Every reply from every connected LinkedIn account arrives in one inbox with the full history behind it.
- **Multi-account management:** Run several LinkedIn accounts from one workspace, each with its own campaigns, limits, timezone, and proxy, plus a shared blocklist.

**Strengths:** Runs in the cloud with dedicated proxies, so you don't rely on a browser tab; Follow-ups wait for acceptance and every sequence stops on reply; Flat $49 per account pricing with all features and a 7-day free trial; Import directly from post engagers and Sales Navigator for higher acceptance rates

**Limitations:** Only expands on LinkedIn, so no other channels are covered; Paying per connected account gets expensive for large account fleets; Requires trusting an automation tool with your LinkedIn accounts
